The project’s name combines the Greek words gonia, meaning angle, and iris (iridos), meaning rainbow. Goniris is an installation which permits artists to chromatically alter the surface of their projects to their favor, on the spot, without having to commit to a definite result; This is done through the hidden hues of the daylight present in our everyday life. We have come to assume an object is the element which, in its characteristics, shows the value of color. Daylight, instead, is thought to only bring the possibility to see them away from darkness, forgetting it is also the main protagonist when creating an ambient or changing our perception of volumes and geometry through shadows. Goniris then uses glass, prismatic surfaces, and iridescent films to work with incident light and project colors on a planar state or through two-dimensional grid onto the inside of a space. The optical guides support the artist to work with a visual, 3D oriented balance and help make decisions in the creative process when experimenting with palettes. It can be replicated in any “workshop” architectural typology, most specifically, industrial constructions which revolve around high trusses and open, free spaces artists usually seek for easier material management and hygiene. It is designed to support artists free themselves from constricted, individual thought processes, and rely on natural resources to influence and become part of their mind for more truthful creations.
